Hope you weren't just watching "The Flash" for Harry Potter alum Tom Felton. According to multiple reports, Felton won't be returning as a series regular in Season 4, and he's currently not booked to come back on a recurring or guest-role basis. That could change, but for now it sounds like he's out.

Felton joined "The Flash" in Season 3 as Barry Allen's (Grant Gustin) CSI supervisor Julian Albert, and as a love interest for Caitlin Snow (Danielle Panabaker). But Season 4 is jumping ahead six months, with Barry trapped in the Speed Force, and it sounds like Julian will no longer be on the team.

Julian was not seen in the Season 4 trailer, and Felton was not at San Diego Comic-Con. We do know he'll be playing Daisy Ridley's brother Laertes in the movie "Ophelia," since he was recently in Prague shooting the movie. But in terms of "The Flash" ... he could always pop up again later, there's just no news on that front right now.

"The Flash" did, however, announce some other casting: Neil Sandilands will play villain Clifford Devoe, a.k.a. The Thinker, and Kim Engelbrecht will play The Mechanic, with Danny Trejo cast as bounty hunter Breacher.

"The Flash" Season 4 premieres Tuesday, October 10 at 8 p.m. on The CW.
